To @ZZ whom t muy 0001061112.'

Be it known that 1, AUGUST H. Orres- MAN, a citizen of Germany, residing at 1ndianapolis, in the county of Marion and State of indiana, have invented a new and useful Electrical Curling-Iron Heater, of which the following` is a specification, reference being had to the accompanying drawings and to the letters and figures of reference marked thereon.

This invention relates to an electrical heater of the type that is hollow or ovenlike in which curling irons or other articles may be moderately heated, the invention having reference in particular to a portable harter that may be placed and used where most convenient.

An object of the invention is to provide a heater which shall be so constructed as to permit it to be safely used where most convement, as upon furniture in apartments without danger of injuring the furniture.

Another object. is to provide an improved electrical heater which shall be of simple and inexpensive construction and be adapted for heating various articles either within the heater or on the outside thereof, and which shall be durable and economical in use.

With the aboveanentioned and other objects in view, the invention consists in an improved portable electrical heater including an improved oven, of such construction as to be adapted to be readily repaired if necessary; and, the invention consists also further in the novel parts and in the combination and arrangement of parts as hereinafter particularly described and further set forth in the appended claims.

Referring to the drawing,#Figure 1 is a side elevation of the improved heater as preferably constructed; Fig. 2 is a vertical central sectional elevation of the heater on an enlarged scale; and, Fig. 3 is a transverse section on the line III-H1 in Fie'. Q.

1n the several figures of the drawings corresponding or like reference characters indicate corresponding parts or features of construction herein referred to in detail.

As preferably constructed the improved heater comprises a slab-like base l which may be composed of wood or other suitable material and preferably is oblong in plan. The bottom of the base preferably is provided with a suitable pad 2 composed of felt or other material. The lower portion Serial No. 588,54.

of the base has a cavity or chamber 3 centrally arranged therein from which a channel l extends to one of the ends of 'the base, the upper portion of the base having` a central aperture 5 extending down to the cavity. The base has a suitable pedestal centrally thereon which preferably is made separately and comprises a foot portion G on which is a stem T having a head bar S there on, the top of the bar preferably being longitudinally inclined so that its lower portion is most nearly adjacent to the end of the base that has the channel 4 therein. T he pedestal has a vertical channel 9 therein that is arranged to continue from the aperture 5, the foot portion 6 being secured upon the base preferably by means of bolts 10 and 10 having their heads in the cavity 23 and nuts 11 and 11 upon the foot portion. 'lwo binding posts 12 and 13 are arranged in the cavity 3, being secured in the upper portion of the base under the foot portion i3 of the pedestal, and circuit wires 11i and 15 are connected to the binding posts respective-ly and extend through the channel in an insulator 1G, the wires being connected to a suitable plug or electrical connector 17.

The oven part of the heater comprises a casing 18 which preferably is cylindrical and is arranged upon the head bar 8, being inclined longitudinally and has an aperture 1:9 in alinement with the channel 9, and the casing is secured in place by means of a clamp plate 2O arranged on the inner side of the casing and to which screws 21 and 521 are. connected and extend through the head bar. The higher end of the casing has a curved head portion from which au annular collar 23 extends into the casing. A head Q4 is removably inserted in the opposite or lower end of the casing and is secured therein by means of screws 25, and the head preferably has a stud 2G' central on its inner side. Preferably the head has a liner on its inner side composed of material that will tend to prevent heat from being communi cated to the head, and preferably a pin 2O is inserted in the stud. A hollow core '29 is arranged in the casing at a distance from tht` wall thereof` one end of the core einbracing the` collar 23 and being` centered thereby. the opposite end of the core preferably having a flared extremity 8O that is seated against the liner 27, the core having suitable openings receiving the pin 28. A.

heating coil 31 is suitably arranged on the core and has terminal wires 32 and 33 that extend through the channel 9 and are connected to the binding posts 12 and 13 respectively, the wires being properly insulated. Preferably the coil has a suitable covering 3e tending to prevent radiation of heat to the casing.

The cavity 3 in the base preferably has a cap plate 235 therein that has side members 36 and 37 engaging the opposite sides of the cavity to retain the cap in place so as to afford a backing iior the pad 2 and to close the cavity.

In practical use the electrical connector or plug 17 properly connected with an electrical circuit on which an electrical eurrent is conducted to the heater coil, result* ing in the oven becoming moderately heated or sn'llicient for the purpose of heating curling irons or other articles which may be conveniently placed in the oven. The heater may be placed upon furniture without resulting in damage thereto, and various articles or substances may be placed upon the top of the oven to be .slightly heated or warmed.

Having thus described the invention, what is claimed as new is:

1. An electrical heater including a casing having a curved head on one end thereoi? and an annular collar extending ifi-om the head, a head removably secured in the opposite end of the casing, a hollow core having one end elastically embracing the collar and seated on a portion of the curved head, the opposite end of the core being fiared and elastically supported on the removable head, and a heater coil on the core.

2, An electrical heater including abase, a hollow pedestal secured upon the base and having a head bar on` its top, a hollow casing secured to the top of the head bai' o'l the pedestal and having an annular head in one end thereof7 a head secured in the opposite end of the casing, a hollow core supported by the two heads, the core having slightly elastical connections with the heads, a heater coil on the core, and circuit wires connected 4with the coil and extending through the hollow pedestal.
